R-AIR Atmospheric Sealed Air Insulated Switchgear

Product Overview

R-AIR atmospheric sealed air insulated switchgear is a fully insulated &fully enclosed switchgear that uses clean dry air as the insulating medium, uses vacuum arc extinguishing as the arc extinguishing method, and has been type tested.
R-AIR atmospheric sealed air insulated switchgear not only meets the basic needs of power users for the safety, reliability and continuity of power equipment, but also provides users with new value in compact, intelligent and environmental protection; It is suitable for public distribution network primary and secondary distribution stations, intelligent buildings, industries, infrastructure and other occasions.

Product Features

Environmentally friendly design

The treated dry clean air is used as the insulating medium, and the electrical clearance in the cabinet is 125mm to ensure the electrical performance and compliance.

Fully insulated and fully enclosed design

The main primary electrified devices and components are enclosed in the stainless-steel welded gas cabinet, completely eliminating the contact of personnel and preventing the impact of dust, moisture, foreign matters, small animals, etc. It has the design of atmospheric fully enclosed and fully sealed gas cabinet, which can be used in high altitude areas. The design of the air cabinet with pressure relief valve and the high-strength armored outer sheet metal cabinet with pressure relief channel ensures the safety of operators.

High altitude adaptive design

There are two kinds of air cabinet pressure design, namely, atmospheric and 150KPa. According to the needs, the design mode with pressure can be selected in high altitude areas.

Large current redundancy design

Combined application of 1250A/25KA and 630A/25KA should be more leisurely for high-capacity systems.

High reliability design

The driving form of the steel spindle of the circuit breaker ensures the stability of the mechanical characteristics of the circuit breaker in the whole life cycle. The operating mechanism with a mechanical life of 20000 times ensures the high reliability of the overall switchgear.

Compact design

The width of standard circuit breaker cabinet is 460mm, which can easily meet the requirements of switching posts or other compact applications.

Multiple expansion mode design

Side expansion and top expansion, shared air cabinet and independent air cabinet and other various expansion and combination modes can better adapt to various electric field combinations.

Intelligent design

The intelligent control system and sensors are combined and applied, and the communication function of the device could be used to connect with the DAVID CLOUD system based on Internet of Things technology and cloud computing, or with other systems required by users.
